摘要: In this paper, a technique is presented for measuring the harmonic impedances of an unbalanced three-phase distribution feeder. The uses transients in bus voltages and feeder currents generated by several close-trip operations shunt capacitor bank. work based on assumption that impedance does not change over time during which switching are performed. Mathematical development verified with laboratory field tests. provided good measurements up to 1.5 kHz given sizes. Statistical indices were developed assess accuracy estimated values.
